150kHz 3A BUCK DC-DC CONVERTER

AP3003

General Description

Features

The AP3003 series of regulators are fixed frequency

PWM buck (step-down) DC/DC converter, capable of

driving a 3A load with excellent line and load regula-

tion. These regulators include internal frequency com-

pensation and a fixed frequency oscillator so that they

are easy to use. A system adopting AP3003 requires a

minimum number of external components to work.

3.3V, 5V, 12V Fixed (±4% Tolerance) and Adjust-

able (±3% Tolerance) Output Versions

Guaranteed 3A Output Load Current

150kHz Fixed Frequency Internal Oscillator

Input Voltage Range up to 32V

Requires only 4 external components

High Efficiency up to 90%

Excellent Line and Load Regulation

TTL Shutdown Capability

A standard series of inductors, optimized for use with

the AP3003 series, are available from several manu-

facturers. This feature greatly simplifies the design of · Low Power Standby Mode, I Typically 80µA

switch-mode power supplies.

Built-in Current Limit Protection and Thermal

Shutdown Circuit

These ICs are available in TO-220-5 and TO-263-5

packages.

Applications

LCD Monitor and LCD TV

On-Card DC-DC Converter

DVD Recorder

PDP
